Hydronic Circulating Pump Flanged 3/4HP MPN:1EF031LF

Featuring a unitized mechanical seal design with a stainless steel drive mechanism that puts less torsional stress on the seal bellows, this BELL & GOSSETT hot water circulating pump also has an open seal chamber design that helps reduce heat buildup and increases particle removal. Bearings are permanently lubricated with Polyrex™ grease for maintenance-free operation. Pump’s 1-pc. design eases seal replacement while the motor, coupler, seal and impeller can all be repaired or replaced without having to remove the pump from its piping. Model is ideal for use as a replacement pump with the flange-to-flange and intake/suction dimensions identical to many legacy Series 60 models
